Description

A device for drying mushrooms

technical field

The utility model relates to a drying device, in particular to a mushroom drying device.

Background technique

Shiitake mushroom is a fungus that grows on wood. At present, shiitake mushrooms are also grown in artificial greenhouses on the market. Because of its delicious taste, refreshing aroma and rich nutrition, it is known as the "Queen of Plants". Shiitake mushrooms are rich in vitamin B group, iron, potassium, and vitamin D. They are mainly used to treat loss of appetite and lack of energy and fatigue. They are deeply loved by people. Now along with the development of planting technology, and in order to meet the market demand, the artificial planting of shiitake mushrooms develops rapidly. After the shiitake mushrooms are mature, the processing procedures such as picking, drying, and storage are carried out, so that they can be eaten at any time.

The processing of shiitake mushrooms is simple, and in the whole processing procedure, drying is the most important. The current drying of shiitake mushrooms generally uses a simple drying oven for drying, and its overall design is not reasonable enough. Some use electric heating wires to directly dry shiitake mushrooms, which is likely to cause uneven drying. The surface of shiitake mushrooms has been fully dried and the internal moisture There are still many phenomena that affect the drying quality of mushrooms. The Chinese invention patent with the application number of 201310756468.9 applied for a shiitake mushroom drying equipment, including a drying box, which is a cabinet structure, the front of which is an oven door, and a power distribution control box is installed on the upper part of one side for drying. There is a temperature and humidity sensor inside the box, and a temperature and humidity display device is installed on the outside of the drying box. There is an air inlet on one side of the drying box, and an air outlet on the other side of the drying box. The interior of the drying box is provided with a plurality of baffles horizontally from top to bottom, and an outlet pipe connected to the vacuum pump is arranged at the air outlet. The number of air inlets is several, and they are evenly distributed on one side of the drying box. Each air inlet is connected to an inlet pipe, and the inlet pipe is connected to a dustproof device, and a heating device is provided inside the side of the drying box provided with the air inlet. The device has a dust-proof effect, but the racks for placing the shiitake mushrooms are fixed and difficult to disassemble and clean, and the moisture discharge and air convection in the box are lacking, which is not conducive to the drying of the shiitake mushrooms.

Utility model content

In view of the above-mentioned deficiencies, the technical problem to be solved by the utility model is to provide a shiitake mushroom drying device with reasonable overall structure design, high heat utilization and fast drying speed. The moisture content is used to control the automatic stop of heating to ensure the drying quality.

In order to solve the above technical problems, the utility model is realized through the following technical solutions:

A drying device for shiitake mushrooms, comprising a box body, a box body door hinged with the box body, a controller, a supporting plate for placing shiitake mushrooms and spaced in the box body, a temperature sensor and a humidity sensor arranged in the box body, The box body includes an outer layer and an inner layer, and microwave heating tubes are arranged at intervals on the two side walls of the inner layer. Connection, its output end is electrically connected with the microwave heating tube after passing through a current controller, the supporting plate is connected with the box body through a sliding guide rail, an air inlet hole is set at the bottom of the box body, and an air outlet hole is set at the top of the box body, The air inlet is provided with two layers of filter screens, and the interlayer formed by the two layers of filter screens is filled with activated carbon.

In the above solution, there are 4 supporting plates in the box, and the bottom of the supporting plates is a hollow grid. Of course, the number of supporting plates can also be determined according to the size, height and drying requirements of the actual box.

In the above scheme, in order to allow the moisture to be released freely during the drying process of the shiitake mushrooms, the air outlet can be provided with self-hanging louvers.

In the above solution, the inner layer may specifically be a thermal insulation layer provided with thermal insulation material, and the outer layer may be a reinforcement board.

The utility model has the advantages of:

1. The shiitake mushroom drying device adopts microwave heating, which can realize simultaneous heating of the surface and inside of the shiitake mushrooms, uniform heating and fast heating speed.

2. Equipped with a controller, it can automatically adjust the microwave heating power according to the water content of the air in the box, which is easy to control the drying quality.

3. There is an air inlet hole at the bottom of the box, and an air outlet hole at the top of the box. During the drying operation, the hot air rises and is discharged from the air outlet. At the same time, the cold air is dehumidified by activated carbon and replenished into the box from the bottom of the box. Inside the body, convection is automatically formed to take away the water vapor generated during the drying operation.

4. The utility model utilizes the natural convection formed by hot and cold air without adding blower equipment, which saves electric energy. The utility model is provided with self-hanging louvers at the outlet of the air outlet. When drying, the air pressure in the box rises and the airflow Blow open the vertical louvers to exhaust air. When the drying operation is stopped, the air pressure inside the box is lower than the outside air pressure, and the self-hanging louvers will naturally droop under the action of gravity, and the air outlet will be closed to prevent outside humid air from entering the inside of the box. .
